Fossil Fuel Steam Generator

Hello, I welcome you all in this course on Power Plant Engineering. Today, we will discuss Fossil Fuel Steam Generators. Now, fossil fuel is the fuel which is made in billions of years when the vegetation is buried under the ground and in millions of years may be 100 or 200 million years; this vegetation is converted into the mineral oil or the coal or the natural gases. And this source of energy is non-renewable source of energy. And the major drawback of this source of energy is that; when the heat is liberated at the same time when we burn this fuel heat is liberated at the same time carbon dioxide is also liberated and which causes the global warming. However, in India more than 60 percent power generation is through the burning of fossil fuels. Now, topics to be covered today are; first of all, we will do the classification of steam generations and then we will discuss the working of a few of the classical steam boilers namely Lancashire Boiler, Cornish Boiler, Cochran Boiler and ...

Coal Handling

Hello, I welcome you all in this course on Power Plant Engineering. Last lecture, we discussed about the Properties of the Coal and in this lecture, we will discuss about the Coal Handling. Now, topics to be covered in today's lecture are Outside plant handling of the coal, storage of coal inside the plant, inside plant handling of the coal, coal transfer from one place to other from the coal mines to the power plant side and Pulverized coal handling. So, these topics we will be covering in today's lecture. In a thermal power plant, bulk of the coal has to be used. I will give you an idea. For example 2000 megawatt plant, it is a I mean quite large size of the plant approximately 5 million ton coal has to be consumed per year. 5 million tons means approximately 2000 tons per day on the basis of 250 days, right. So, quite large amount of coal has to be handled. So, this coal has to be brought from coal mines to the plant site, right and from plant site and it has to be stored b...

History of AI from 40s - 90s

Alright, so, welcome to the AI course, from today we are going to talk about the technical aspects of AI. And before I start I want to mention that while I am going to be presenting the course, I have I am really standing on the shoulders of giants in other words, there are a lot of lot of people who have taught AI taught AI really, really well taught AI probably much better than me, taught AI I have learned AI lot from them and so on so forth. And I have learned from many such people and the slides that I will be using will be stolen from different places of course with you know, some, some permission, some permission, I would say. And so, because of that, you know, we will be sort of taking interesting bits from wherever I found and combining them in the course, I should also point out that I am going to credit all the people that have taken slides from in the first slide, not on individual slides, but you know, I really, really thank them for developing this course for me and ...

Mountings and Accessories-I

I welcome you all in this course on Power Plant Engineering. We have amply discussed in the previous lecture about the steam generators. And now we will discuss about Mounting and Accessories of steam generators. Mountings are important in a steam generator; I will give you an example for example in a car, proper control of a car or monitoring of a car steering is required, brakes are required without them you cannot run the car right. For carrying the luggage, the carrier is required. So, these are all mountings of the car. Similarly, in case of the boilers, mountings are required for the proper operation and safety of the boiler because safety of the boiler is very important. And in India we have an act IBR and in it was introduced in 1925 and all the boilers operating beyond a particular range. For example, the volume of the shell is more than 25 liters, it is covered under IBR; if the pressure any pressurized storage of steam is covered under IBR. Any pipe which has diameter m...

Machine Learning

welcome to machine learning for engineering and science applications I am Balaji Srinivasan I am in the mechanical engineering department hi I'm gonna put the Krishna mood I am in the department of engineering design and both of us are from iit madras so if we look at various applications that all of us are using already in real life for example this is Amazon's recommender system some of you might have seen Amazon echo which is a speech recognition system of course everybody has used Gmail spam classifier and this is Google Lexus this is a latest self-driving car all of these use machine learning algorithms in one way or the other our purpose in this course is to try and utilize the same algorithms for more general problems for example medical image diagnosis or for speeding up CFD computations we look at the course aims basically we will try to understand some of the basic machine normal learning models thoroughly with specific emphasis on deep learning which is the current ...

Longitudinal Dynamics

so we will continue with what we were doing in the last class we were looking at a broad picture or perspective of vehicle dynamics so we were looking at how we are going to approach the subject of vehicle dynamics we said that for us though there is a vehicle it has its components and so on when we are studying vehicle dynamics we said the center of this whole thing is the mathematical model so mathematical model comes from our good old euler-newton equations and this has an input and an output remember that when we looked at the dynamics okay which is defined by using these mathematical equations they are classified into what we called as longitudinal dynamics lateral dynamics and vertical dynamics okay we said that we classify the dynamics what we are going to study using this mathematical model into a longitudinal lateral and vertical dynamics we also said that for these of understanding its effect we may most of the times delineate or decouple them and study them in isolatio...

Boiler Performance

Hello, I welcome you all in this course on Power Plant Engineering. We have amply discussed about the boilers normal boilers high pressure boilers their mountings and necessaries. Now today we will discuss about the performance of the boiler. Because performance of the boiler is a very important parameter to assess the efficiency of the power plant right and for example, if we if we take a car. So, before we purchase a car, we assess the performance of the car and the performance of the car is assess how much mileage it is giving per liter how much kilometers it is covering . In similar way, the boiler performance is also assessed and there are different parameters to assess the performance of the boiler. Now, the first parameter is evaporation rate. How much water is getting converted into this? So, there are certain units for evaporation rates for example, this is kg per hour. Now, kg per hour per meter square, kg per hour per meter square; because there are different boilers having ...

Mountings & Accessories-II

I welcome you all in this course of Power Plant Engineering. Today, we will continue to discuss the Mounting and Accessories of steam generators. Topics to be covered today are the boiler mountings, remaining boiler mountings. Some of the boiler mountings we have already discussed in the previous lecture, and some of the boiler mountings will be discussing in the current lecture, and some of the boiler accessories we will be discussing here. So, let us start with a boiler mountings. There is a fusible plug which is required in almost all fire tube boilers. If fire tube boiler is a boiler, where in the shell the water is filled and there is a tube that maybe 1 tube or maybe 2 tubes or 3 tubes which are carrying the hot fuel gases which are burned in the combustion chamber of the boiler and these hot gases are surrounding by the water. Water is not filled up to the top, it is filled up to the certain level, right, in certain level is maintained. And, when these gases they when they ...

Material Property Landscape

So far, we have looked at the materials that changed the history. So, we looked at wood, ceramics, fiber and cloth, and so on. So now, let us look at the concept of what do we mean by material science and what do we mean by materials engineering. Or, in other words, let us see what is -- how these two fields of study have been classified. So, the material science per se actually deals with the structure-property correlations. So, basically, what is the structure and what is the property that is obtained in the material through that structure? So, material science deals with the structure-property correlations, while materials engineering deals with designing or engineering of the structure of a material for specific application. So, basically it relies on structure-property correlations, and it takes from there, and then tries to design structures or components for a material -- of a material, for a specific application in mind. So, what do we mean by structure? A structure is nothing ...

Coal Properties

Hello, I welcome you all in this course on Power Plant Engineering. Now we have discussed boilers and the performance of the boilers in the previous lectures. Now the coal is used in the thermal power plant. Coal is the main fuel which is used in the thermal power plants. And today we will discuss about the properties of coal. And we will discuss topics to be covered today are first of all discuss about the coal, analysis of coal, classification of coal, we will talk about the Indian coal and coal beneficiation. Now, regarding the coal is the oldest fuel which is used in the power plant. Actually oldest fuel is the wood; I mean which is used for heat generation or in power plant also earlier the wood was used, but coal is the main I mean for the commercial power generation the coal is the oldest fuel. And the earth has sufficient reserve for the coal for the another let us say 20, 30 years. So, still we can go for the coal based power plants. Shifting earlier many of the power plants w...
